Events in daily life sometimes occur symbolically in dreams. 27 , a boy is having difficulties on the school playground because a bigger boy keeps bullying him.
答案：(C) For example
前面說「日常生活中的事件有時會以象徵形式出現在夢中」，這句舉一個具體例子（一個男孩在操場上遇到困難），For example 符合舉例功能；In general（一般而言）、As a result（因此）、In contrast（相反地）都不合。
本題大考中心未公布逐題答對率，以下不談數據，只談觀念。
四個選項都是很常見的轉承語，中文意思差很遠，照理說不難分，但如果只讀空格所在的那一句，你會看到一個男孩在操場上被欺負的故事，看不出它跟前面有什麼關係，於是只好憑感覺挑。這一格必須回頭看前一句。
四個選項都是轉承語，可見這一格考的是前後兩句的關係，那就把兩句擺在一起。前一句是一句通則：Events in daily life sometimes occur symbolically in dreams（日常生活中的事件有時會以象徵的形式出現在夢裡）。這一句則是一個具體的情境：一個男孩在操場上被大男孩欺負，晚上夢見自己獨自站在操場上面對一頭獅子。從一句概括的話走到一個具體的個案，這就是舉例，用 For example。掛鉤是國中的 I like fruits such as apples and bananas. 那種舉例的動作，只是這裡舉的是一整個情境，所以用 For example 而不是 such as。這一題與 93 年第 26 題正好可以對照著看：那一題是空格在通則句裡，要靠下一句 For example 舉的例子反推答案；本題則是空格就在 For example 的位置上，要靠前一句的通則來確認。看到 For example，就要意識到前後兩句是「通則與個案」的關係。
In general（一般而言）：方向剛好相反，它是從一堆個案收攏成一句通則，而本句是從通則走向個案。As a result（因此、結果）：表因果，但男孩的故事不是「日常事件會象徵性地出現在夢裡」所造成的結果，它只是這句話的一個例子。In contrast（相較之下）：要把兩件不同的事並排比較，而本句與前一句講的是同一件事。
for example（舉例來說）、such as（例如）、occur symbolically（以象徵的形式出現）、have difficulties（遇到困難）、bully sb（霸凌某人）、on the school playground（在學校操場上）。
Basically, there are two kinds of sleep. One is Rapid Eye Movement (REM) sleep. In 21 , the brain waves of a sleeping person are similar to those of a waking person, and the eyes move about rapidly under the closed lids. 22 kind of sleep is Non-Rapid Eye Movement sleep.
Scientists have discovered that dreams happen mainly in REM sleep. Everyone dreams about 20 percent of their sleeping time. 23 people who say they never dream show about 20 percent of REM sleep. 24 these "non-dreamers" do their sleeping in a laboratory 25 researchers can wake them up and ask them whether they were having dreams the moment before, it 26 that they dream as much as others.
Events in daily life sometimes occur symbolically in dreams. 27 , a boy is having difficulties on the school playground because a bigger boy keeps bullying him. He may dream at night of being alone in the playground, 28 a lion. At other times the dreaded event from daily life simply occurs in a dream in its real-life form; 29 , the boy dreams of being bullied by the bigger boy.
30 scientific research, we have known more about the relationship between sleep and dreams. However, why a dream will take a certain symbolic form is still a mystery.
